Abstract
The utility model discloses a kind of dioxy sand casting moulds of extra-high-tension cable seat type insulator, including babinet and dioxy sand obturator, the dioxy sand obturator to be located in babinet, and the cavity shape in dioxy sand obturator is identical as the external surface shape of seat type insulator；The outer shape of dioxy sand obturator is rectangle, is matched with shape in babinet, the top of dioxy sand obturator is provided with molten iron inlet.Obturator and lower obturator are provided with multiple stomatas on dioxy sand obturator；The stomata is connect by tracheae with carbon dioxide gas source.The utility model uses dioxy sand casting mould, since dioxy sand is thicker than common damp fineness of sand and high temperature resistant, and becomes firmer by being combined with carbon dioxide, so as to resist the impact of molten iron, keeps an any surface finish for type insulator perfect.The dioxy sand casting mould that the utility model uses is than common damp sand mould strength higher, and to substantially increase a type insulator yield rate, yield rate can reach 90% 98%.
Description
Technical field
The utility model is related to a kind of casting mould, the dioxy sand of especially a kind of extra-high-tension cable seat type insulator is cast
Mold.
Background technology
It is a kind of extra-high-tension cable seat type insulator of certain external company's consigned processing shown in Fig. 1, this type insulator
Surface requirements galvanizing, thus it is higher to the quality requirement on surface.Traditional casting method is using damp mould tide core shown in Fig. 2
It is cast, since casting tooth is than shallower, damp sand is not firm enough, and molten iron impact force is big when cast, and the often drop in cavity causes
Very high rejection rate can generally reach 50% or more.
Utility model content
To solve the above problem of the existing technology, the utility model will design a kind of extra-high voltage that can improve yield rate
The dioxy sand casting mould of cable block type insulator.
To achieve the goals above, the technical solution of the utility model is as follows：A kind of extra-high-tension cable seat type insulator
Dioxy sand casting mould, including babinet and dioxy sand obturator, the dioxy sand obturator are located in babinet, the filling of dioxy sand
Internal cavity shape is identical as the external surface shape of seat type insulator；The outer shape of the dioxy sand obturator is square
Shape is matched with shape in babinet, and the top of dioxy sand obturator is provided with molten iron inlet.
Further, the babinet includes top box and nowel, and the top box connects structure with nowel by bolt arrangement
At entire babinet.
Further, the dioxy sand obturator is divided into obturator and lower obturator；Upper obturator and lower obturator
Interface it is consistent with the interface of top box and nowel.
Further, obturator and lower obturator are provided with multiple stomatas on the dioxy sand obturator；The case
Body top plate is provided with multiple holes with bottom plate, corresponding with the stomata of dioxy sand obturator upper and lower part respectively.
Further, the cavity in the dioxy sand obturator is located in lower obturator.
Further, one end closing of the stomata in dioxy sand obturator.
Further, the stomata is connect by tracheae with carbon dioxide gas source.
Compared with prior art, the utility model has the advantages that：
1, since the utility model uses dioxy sand casting mould, since dioxy sand is thicker and resistance to than common damp fineness of sand
High temperature, and become firmer by being combined with carbon dioxide, so as to resist the impact of molten iron, make a surface for type insulator
It is bright and clean perfect.
2, since the dioxy sand casting mould of the utility model use is than common damp sand mould strength higher, to significantly
A type insulator yield rate is improved, yield rate can reach 90%-98%.

Fig. 1 is a structural schematic diagram for type insulator.
Fig. 2 is the structural schematic diagram of existing damp sand mo(u)ld tool.
Fig. 3 is the structural schematic diagram of the utility model.
In figure：1, seat type insulator, 2, molten iron inlet, 3, top box, 4, nowel, 5, upper obturator, 6, lower obturator, 7,
Stomata.
Specific implementation mode
The utility model is further described through below in conjunction with the accompanying drawings.As shown in figure 3, a kind of extra-high-tension cable seat type
The dioxy sand casting mould of insulator, including babinet and dioxy sand obturator, the dioxy sand obturator are located in babinet, and two
Cavity shape in oxygen sand obturator is identical as the external surface shape of seat type insulator 1；The outside of the dioxy sand obturator
Shape is rectangle, is matched with shape in babinet, and the top of dioxy sand obturator is provided with molten iron inlet 2.
Further, the babinet includes top box 3 and nowel 4, and the top box 3 and nowel 4 are connected by bolt arrangement
It connects and constitutes entire babinet.
Further, the dioxy sand obturator is divided into obturator 5 and lower obturator 6；Upper obturator 5 and lower filling
The interface of body 6 is consistent with the interface of top box 3 and nowel 4.
Further, the upper obturator 5 of the dioxy sand obturator and lower obturator 6 are provided with multiple stomatas 7；It is described
